This invention relates to an improved locking device for automobile brake and clutch pedals and it has more particular reference to that species of invention utilized as safety appliances to lock a clutch pedal in inoper- 'atlve position or a brake pedal in 'bralrefap-- automobile is left- Aunoccupied in order to guard against and plylng position when the minimize theft and operation of by unauthorized persons.

am aware that numerous endeavors have been made in this artV to different types of devices for this purpose, and it is therefore my principal cbj ect togenvorally improve upon known patented and p marketed devices by` providing one which is 3 description and drawing.V

In the drawing:

lgure 1 is a view 1n elevation and section showing a retaining' device constructed in accordance With the present invention and indff eating its relationship'to the Hoor board and pedal structure. Y

VYThis casing includes a sleeve-like portion 15 surrounding aneoscillatory shaft 16, and a barrel lock 17 located lon the exterior of the housing and constructed to accommodate a locking key 18. This barrel lock vis provided With a suitable barrel 19 having a bolt 20. It will befnoted` that Y. the shaft l'carries a retention gear 21 con fined inthe housing and that the portion l5 of 'the lock casing is formedwith elongated gear teeth 22 adapted'tomesh With the teeth Moreover Vthe bolt 2O is shown in dotted lines in Figure'l; after the lock `casing is Vsliddoivn inthe slot 13. On the upper Vend of the shaft is an operating crank'handle 23 andsurrounding the-shaft portion 15 isa lift lng spring 24 Whichlnormally holds the lock structure upin-the full Vline'position shown in Figure 1 in Which Aposition it does not in-v tel'fere with the gear 21 or the rotation of l the shaft 16.

YVThis casting is hung from the "under side of thefloor and at its bottom terminatesin Aa right angular tubular guide 27 lwhich serves toi acc-omino?, lv'date a retaining slide V28. vThis *slideis formed on one side with rack teeth 29 ,with which a pinion 30 on the shaft meshes. The

slide 28 isA-providedfwith a toothed .headl cooperable With the teethll on the' aforesaid pedal attachment or hea-'dg- W'ith this arrangementvitis obviousthatr when they pedal is depressed'to the dotted'line position as shown in Figurel7 this brings the head 11 'eppositethe headil..` Consequently teeth of the when the slide 2,8 is actuated the tvvo'hheads come togetherto hold'the pedal down "in lthis, inoperative state. It is quite levident that in order tojactuate the slide 28 all that is necessary is to. oscillate the hand cranl`23 in the. directionof the arrows shown' in lfligure2.` To complete lock casing`14 A portion of `the shaft .extends doivnv Sil theV operation, the Y y ioe oscillation of the shaft 16. To hold the casing down against the tension of the spring, the key controlled lockingrbarrel 19 is actuated to in turn actuate the bolt 20, thus engaging the keeper underneath the gear 21.

A careful conside l description in conjunction Withftlie drawing will doubtless vpermit the reader to obtain a clear understanding ot the construction, operation and advantages .of therzinyention. Therefore, a more lengthy description is regarded unessential. Y

Minor changes in shape, size and rearrangenient of parts coming i'vithin 'the riield of invention claimed may be resorted to in actual -piacticeit desired.
